More Information
Summary:In accordance with the teachings of a prior application, in a telecommunications network, a local database stores destination telephone number information derived from a more global database, shared by a plurality of switching systems usually remote from all or most of the systems. One or more bit maps are used to store key indicators for each telephone number for which information may be required. This invention relates to a method and apparatus for automatically updating the local database, by recognizing that a switch identified as serving a directory number does not have access to the line corresponding to that number; when this condition is discovered, the global database is increased and the local database updated.
